So, I played with it with my racket settings and a setup I'd like to try out:

weight: 340.48g
Balance: 32
Swingweight: 335

Final weight: 352.48
Final balance: 32
Final swingweight: 365
weight mass 1: 7
weight mass 2: 5

The above give me locations of (roughly) 14 and 57, which is OK.

I, too, get a pretty big difference in swingweight when I plug the starting values, weights, and locations into Steve's spreadsheet. It ends up saying the swingweight is 346.

Sorry I can't post the images like someone else did, don't know how to do that. Any idea why the swingweights are so different, or which one is closer?

Thanks,
Andrew
Andrew, if the 2 spreadsheets don't agree then it's impossible I've found. If you try to get too big a swingweight it may not work and Steves spread is pretty accurate(to about 0.03 off) so 2 things you can do: Lower the desired swingweight unfortunately, or mess around with the mass in location 1(the one in white) until both spreadsheets agree
